Psyllium (psyllium) is native to Iran and India, and its seeds are part available, usually grind the seeds shell after processing, can absorb about 50 times expansion, seed shell contains soluble and insoluble fiber, ratio of about 3: 1, common in Europe and high-fiber diet, supplements are as fibrous. The study found that fiber psyllium seed is contained in all the most abundant sources of food, usually used to treat constipation in traditional therapy in China and India, psyllium for the treatment of diarrhea, hemorrhoids, bladder problems and high blood pressure; also commonly used in anti-skin irritation, including Ivy toxicity and insect bites.
A large number of data show that the fibers can not only prevent gastrointestinal diseases, but also prevent some fatal disease, the study noted that, as a lack of dietary fiber, will increase food residues remain in the intestinal tract, and increase the generation of carcinogen and its contact time with the mucosa of the intestinal wall, easy to cause colorectal cancer or suffering from other diseases of chance, on the contrary, if the existence of an appropriate amount of fiber, type and number of intestinal microbes may change, because the other fibers absorb water retention and reduced carcinogens or the concentration of harmful substances, and because of the promotion of intestinal peristalsis, accelerate its discharge, reducing time and intestinal mucous membrane contact, and can prevent or reduce the prevalence of colitis intestinal disorders.
In Europe, psyllium is often added as a high-fiber breakfast fibrous additives, a study published in the American Journal of Clinical Nutrition (American Journal of Clinical Nutrition), experiment by researchers at the University of Kentucky conducted also found foreign psyllium can lower cholesterol, reduce the risk of heart disease for clinical significance. This study allows patients with hyperlipidemia for eight weeks, eat 10.2 grams of fiber a day psyllium seeds, but also to design a low-fat diet, so that they no longer eat too much fat. It was found that psyllium can additionally increase the lipid-lowering effect of a low-fat diet, total cholesterol, it can be further reduced by about 4%, while the low-density lipoprotein (LDL, or bad cholesterol), it again reduced 7%, for the good cholesterol is not affected.

For many obese people, heart disease is a major health hazard, which is caused due to high LDL cholesterol, eat more high-fiber foods can lower bad LDL cholesterol, so if it can eat more high-fiber foods, for heart disease prevention of great value.
